Finally I decide to remove the node from the cluster and rejoin, and SOLVED. A member having less interfaces than the maximal number in the cluster (the reporting member) may not be working properly, as it is missing an interface required to operate against a cluster IP address, or a synchronization network. Make sure to do this on the Primary node (filer01). By default, this port is allocated dynamically in such a way as to ensure that no two nodes on the same host computer receive the same port number, so it should normally not be necessary to specify a value for this parameter. Once the maximum number of retry attempts has been reached, if the job has still not restarted successfully, Job Manager will kill the job. This command prompts you to restart the service. The process will restart only if the number of abnormal terminations during the period specified by the reset time is less than the number of restart times.
